My invention relates to improvements in spray nozzles.

The object of my invention is to provide a spray nozzle adapted to spray a thin film of water or other liquid on a flat surface and having means whereby it can be adjusted to vary the spray of water or liquid discharged therefrom, and maintaining'the same thickness of spray throughout its entire length of spraying opening.

Another object of my invention is to provide a nozzle more particularly adapted for urinals whereby there will be no splash of the water on the feet of the user and at the same time allowing of the adjustment of the nozzle while it is in operation, whereby the desired adj ustment maybe made at any time.

A' further object of my invention is to provide a nozzle of this character which is made of few parts, readily adjusted and having certain details of structure and combination of parts hereinafter more fully described.

In the accompanying drawings L- lligure 1 is a vertical sectional view of a y urinal showing my improved spray nozzle character it is very essential that the entire I vertical bach plate 5 thereof be sprayed with a thin vlilm of water, yet said film being so arranged that the water will not spray or splash on the .feet of the user standing at the point 5.

The nozzle 4l consists of a tubular threaded portion 6 whereby it may be attached to the hood 3 of the urinal by means of the nuts 7 and 8, as shown in Figure 1 of the drawings. The lower end of the tubular portion 6 is ofi' set at an angle as indicated at 9, and provided with a vertical wall 10, and at the lower end thereof is provided with obliquely arranged cylindrical tubular portion 11 arranged at an 1927. serial No. 200,661.

angle of approximately 45o to the portion 6. Within the obliquely arranged tubular porktion 11 is an inwardly extending lug 12 prO.- vided with a screw threaded opening 13'. Surrounding the lower end of the obliquely tti, arranged tubular portion lland sliding on 'a true plane therewith is a cylindrical member 14 having the closed end 15 and having at one side theoutwardly extending spray Aplate 16 extending a considerable distance f5@ beyond the rlhe Acylindrical member 1/1 has a slot 17 entending a little over one half way around, and the lower end of the slot is flushwith the upper face of he spray plate 16, as clearly shown in llligin'es 2 and 3 of the @5 drawings. The closed end 15 of the plate is provided with an opening 18 through which kpasses the adjusting screw 19, whichfhas its inner end screwed into the opening 13 in the lug 12. Surrounding the screw, between the 7@ lug 12 and the closed end 15, is a coil `spring 2()V which is normally exerting outward pressure on the member 111 to force the same outwardly. The screw19 is off center and therefore the member 14 can not rotate on the tubu- 75 lar member 11.

Y By adjusting the screw 19 it will be seen that Vthe closed cylindrical memberr 14E Vis `moved on the obliquely arranged cylindrical portion 11, and thus the distance between the 8@ lower end of the cylindrical portion'11 and the closed end 15 of the cylindrical portion 14 isvaried for' increasing or decreasing the thickness of the film of water passing from the nozzle. l j l lt will be seen thatthe thickness of the spray in all yadjustments is equal throughout the entire spraying opening. f

Having thus fully described myinvention whatl claimiszv y 1. A nozzle of the character describedcome prising a body portion, a cap enclosing the lower end of the body portion and longitudinally movable thereon and having a slot in one side thereof and means passing through 95 the end of the cap and operated from the outside of the cap for longitudinally adjustring the cap onthe body portion for varying the width of the slot.

` 2. A nozzle of the character described com- '100.

prising a body portion, a cap enclosing the lower end of the body portion and having a slot in one side thereof, and means passing through the end of the cap and having an adjustable connection within the body portion for adjusting said cap for varying the width of the slot.

3. A nozzle of the character described coinprisinga body portion, a cap enclosing the A end of the body portion and having a slot on one side thereof, a spray plate on one side of the cap and surrounding the slot and having its inner face in a pla-ne with the inner face of the end of the cap, a spring nornially holding the cap in an outward position and a screw loosely passing `through the cap and screwed within the body portion and adapted to adjust the cap inwardly against the tension of the spring. sa 4l, A nozzle of the character described coniprising a body portion., a cap enclosing the lower end of the body portion and having a slot in one side thereof and a screw loosely passing through the end of the Cap from the outside and having a threaded connection within water passage of the body portion whereby the turn of the screw adjusts the cap for varyingthe width of the slot.

5. A nozzle of the character described, cornprising a body portion having a lug in the water passage thereof and having a threaded opening therein, a cap enclosing the lower Vend of the body portion and having a slot, a bolt passing through the end of the cap and screwed into the lug for adjusting the said cap for varying the width of the slot.

v6. A nozzle of the character described cornpr-ising a body portion having a threaded opening within the water passage' thereof, a 40 cap enclosing the lower end of the body portion and having a slot in one side thereof, and

a screw loosely passing through the end of the cap and threaded into the opening in the bore of the body portion for adjusting the cap for varying the width of the slot.

7. The nozzle ofthe character described comprising a body portion, a cap enclosing the lower end of the body portion and having a slot in one side thereof and means carried by the end of the cap and cooperating with the body portion within theV water passage thereof for adjusting said cap on the body portion for varying the width of the slot.

r In testimony whereof, l have signed this specification.
